LOW SILHOUETTE COMPRESSION SLIDER Filed Feb. 2o, 196s H T TOR/VZV United States Patent Oiilice 3,127,654 Patented Apr. 7, 1964 3,127,654 LVV SHJHUETE SLIDER Louis II. Morin, Brenn, N Y. (125 Beechwood Ave., New Rocheiie, NY.) Filed Feb. 2i), 1965, Ser. No. 259,9@6 is erstma. (ci. asfissia) This invention relates to sliders for use in connection with separable fastener stringers to couple and uncouple the same. More particularly, the invention deals with what I term a low silhouette spring-locking-type of slider, wherein the walls of the slider are normally cast in spaced relation to each other and the slider is compressed in assemblage of the slider upon the stringers of a fastener.

Still more particularly, the invention deals with a slider structure of the character defined, wherein the pull engaging yoke of the slider has a hook-shaped coupling engagement with one end of the slider wall and a single rivet is employed in assemblage of the yoke with the slider body and, further, deals with provision of means for support of the spring lock of the slider in hold-open position.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

FIG. 1 is a plan view of a slider made according to my invention, with parts of the construction broken away and parts in section.

FIG. 2 is a side and longitudinal sectional view through the slider as shown in FIG. 1, illustrating the normal cast position of the siider in full lines and indicating the compression of the slider in dotted lines, the spring locifof the slider being shown in operative position in full lines and in inoperative hold-open position in dotted lines.

FIG. 3 is an enlarged partial plan view of the contracted end portion of the slider, omitting associated parts and with part of the structure broken away and in section; and

FIG. 4 is a sectional View on the line Ll--d of FIG. 2, omitting background showing.

Considering FIGS. 1 and 2 of the drawing, it will appear that the slider body comprises top and bottom walls It? and Il, generaliy of the same peripheral contour, these walls being joined at the wide end of the slider in a connecting frog or web 12. The wall 11 has, centrally of the inner surface thereof, a raised platform I3, as noted in FIG. 2 of the drawing, and the wide end portion of the wall 1I reduced at its sides, as indicated at I4. This wall is shown in its normally cast position in full lines in FIG. 2 and in its compressed or use position in dotted lines.

The inner surface of the wall lil has side scoop engaging iianges I5, generally of the contour indicated in dotted lines in FIG. 1 of the drawing, and terminating, as indicated at i5', to provide between i5 and the side walls 12 of the frog or web 12 the scoop admission passages, as with other devices of this type and kind.

The wide end portion of the top wall I@ has a raised platform 16, terminating in a shoulder 17, the platform 16 having an integral rivet forming portion It and centrally of the outer end of the platform is a raised rib or lip 19.

The wall Iii has, at the contracted end thereof, a raised and generally U-shaped platform portion 29, note FIG. 3 of the drawing. This portion has, at the contracted end, a crosshead 21, from which extend the parallel sides 22. The inner ends of the sides 22 form stop shoulders 23 in checking movement of the rounded pivot end 24 of a pull 25 in one directional operation of the slider, the

shoulder 17 checking 24 in movement of the slider in the opposed direction.

Adjacent the shoulders 23 and inwardly thereof, the top wall lil has a transversely wide recess 26, which can be referred to as the hold-open recess, into which the pivot end 2li of the pull is adapted to seat when the pivot end is in the dotted line position of FIG. 2 .in support of a spring lock, generally identified by the reference character 27 in hold-open position. It will be understood that the pivot end of the pull can be manually removed from the recess in normal operation of the slider.

The wall Iii, at the contracted end of the slider and beneath the raised portion 2i), has a transverse recess 28, which forms on the inner surface of the raised portion a shelf 29, adapted to be engaged by the hook end 30 of an elongated yoke 31. The hook end 3i? includes a portion 32, which seats in a recess 33 formed in the raised portion 2d and part of the wall lil, as will clearly appear from a consideration of FIGS. l, 2 and 3 of the drawing. The yoke 31 seats on the exposed surfaces of the parallel sides 2.2 and conforms to the angular contour of these sides, as is clearly shown in FIG. 2 of the drawing. The other end of the yoke has an aperture 34 for receiving the rivet portion IS, including the riveted-over head 13 thereof.

The spring lock 27 has an elongated aperture 35, the end 36 of which terminates around the rivet 18; whereas, the other contracted end 37, note FIGS. 1 and 2, terminates in close proximity to the two scoop engaging lock elements of the spring lock, note FIG, 4 of the drawing. The lock elements 3S operate in parallel apertures 39 formed in the wall itl, as clearly seen in FIGS. 2, 3 and 4 of the drawing. The elements 33 are offset, as indicated in FIG. 1, to aline with and engage coupled scoops. Between the parallel apertures 39 is a rib 40, having an angular upper surface 41, which forms a stop engaged by the spring lock 27, or that part: thereof disposed between the lock elements 3S, as clearly seen in FIGS. 2 and 4 of the drawing.

in FIG. 2 of the drawing, the lock element 27 is shown in its operative position in full lines and in its inoperative or unlocked position in dotted lines. The spring lock, by virtue of the long aperture 35 provided therein, is free iiexing and the lock elements 38 are fashioned to engage spaced scoops of stringers of a separable fastener. The rear edge 33 of one of the elements 38 serves as a stop adapted to strike against the Walls 39 of the apertures E@ when 27 is in the locked position and a strain is applied to the stringers, tending to open the fastener, the spring lock 27 being capable of flexure or bowing siightly under the strain during this operation in assuring a positive check and lock of the slider on the Stringer. The moment that this opening strain is removed, the lock element 27 wiil return to its normal locked position, as shown in full lines in FIG. 2 of the drawing. In connection with the foregoing, it must be kept in mind that, in manually operating the slider along the stringers in the coupling of the scoops or closing of the fastener, the elements 3S ratchet over the scoops and it is important to provide free flexure of the lock spring 27 during this operation.

By providing a yoke, similar to the yoke 31, the assemblage of the slider parts is simplified, in that the hook end 3@ of the yoke is simply engaged with the contracted end of the siider and the ends of the yoke 31 and spring 27 are passed over the rivet 15, with both of these members abutting the rib or lip 19, as clearly shown in FIG. 2, and the one riveting operation, as at 1S', securely retains the parts in assembled relationship. The rib or lip 19 further serves to retain the spring lock 27 against movement in the direction of 19; whereas, the lock elements 38 engaging the apertures 39 maintain alinement of the spring lock on the slider wall at all time.
